The whole point of arbitrage is to know (and act on) what other people
don't know, or or don't know yet. In the 1s-precision regime, people
who have access to data that comes to them less than 1s faster than
others don't gain any benefit from it. With more accurate timestamping,
more accurate reflection of the value of timely data is possible.

As for market management, it will and must go beyond effective human
intervention. Monitoring programs will have to react faster and more
comprehensively than participants; as a result, they will need subsecond
precision even before other components in the system require it. In the
last analysis, trades can be rescinded if necessary, the moral equivalent
of pulling the plug.
